I have the standard solas. It is apparently a 30 lumens light. The badging is simply for niterider solas like the following:

Now niterider has 100 and 150 lumens versions of the solas. Will it be worth it to upgrade? Obviously my current solas is working perfectly.

Also wondering if the cygolite 150 would be a significant upgrade. I don't doubt the 150 versions are a bit better, but perhaps not 5X better.
